GUARD FOB STALLS.

Specification of Letters Patent.

Patented Feb. 13, 1917.

Application filed February 8, 1913. Serial No. 747,007.

1 To all whom it may concern Be it known that I, WILLIAM MITCHELL, acitizen of the United States, and resident of Milwaukee, in the countyof Milwaukee and State of lVisconsin, have invented new and usefulImprovements in Guards for Stalls, of which the following is adescriping located near tion, reference being had to the accompany ingdrawings, which are a part of this specification.

This invention has for its object to provide a guard for cattle stallswhich will prevent the animals when driven into the stalls from placingtheir heads through the openings between the stanchions and the stallframes, leaving the only available opening within the open stanchions.

Anotherobjeet of the invention is to provide such guards with means forsimultaneously operating them throughout the line. of stalls.

With the above and other objects in view the invention consists in theguard for stalls as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters ofreference indicate the same parts in the different views:

Figure 1 shows a guard for stalls constructed in accordance with thisinvention the guard being in its open or effective position;

Fig. 2 is a similar view thereof with the guard in its closed orineffective position;

Fig. 3 is'a detail plan view of the guard showing itssupportingconnection with the stall frame; s

Fig. 4: is an end view thereof with the guard bars sectioned to show theconnecting means thereof; and,

Fig. 5 is a detail view of the pivotal con nection of the guard barsbefore being assembled.

In these drawings 10 indicates a stall frame of tubular metalconstruction with the stanchionsll mounted thereon and connected withthe sill 12 in an ordinary manner to allow a freedom of movementlaterally.

A pair of levers 13 are pivotally connected at an intermediate point'tothe upright standard of the ,stall frame forming a division between thestall, one of said levers bethe lower end of the standard and the othernear the upper end of the standard and to the ends of these levers arepivotally connected vertical guard bars 14 which because of thecorresponding location of the pivotal connections of the two leversremain arallel during swinging movements of the ever, but move nearertogether or farther apart as shown in Figs. 1 and 2 'when the leversswing from one position to another. Preferably the pivotal mounting ofthe levers on the standard is effected by means of a bracket arm 15extending from.

the lever to partially embrace the standard and provided with a pivotpin 16 passing through it and through the standard and lever as bestseen in Fig. 3. This arm 15 as-- sures a strong pivotal connectionbesides serving as a stop for limiting the swinging movements of thelever by engaging the standard when the lever is in its horizontalposition, or the position in which the guard bars 14 are farthest apart.Any suitable form of pivotal connection may be provided for the guardbars 14, but the form shown in Fig.5 is preferable wherein the tubularguard bar has a' notch'17 out .in its end and a sleeve 18 is fitted overthe end of the tubewith an inwardly set pivotal ear 19 fitting withinthe notched portion, the unnotched edge of the tube then being turnedover the edge of the sleeve 18 in the manner shown in Fig. 4-. Thepivotal car 19 forms the pivotal connection for the guard bar and thismanner of connecting it to the guard bar assures a permanent connection.

Any desirable means may be provided for swinging the levers 13. .Asshown a bracket 20 isbolted or otherwise secured to the upper portion ofone end of the upper lever and extends above the stall frame where ithas a pivotal connection with a rod clamp 21 which is adjustably fixedon an operatin rod 2-2 running the lengthof the row or stalls andprovided with suitable means, such as a handle 23, for moving itlengthwise to effect the operation of all of the stall guardssimultaneously.

In operation the rod 22 is moved in a direction to cause all of thestall guards to open out into their extended or effective position, asshown in Fig. 1, at'the time the stanchions are opened and beforedriving the cattle into the stalls. The cattle finding the space betweenthe stanchions and the stall frames occupied by the guard bars 14;

will place their heads through the stan-' chions as desired and thestanchions may then be closed and the rod 22- moved to the otherposition so as to collapse or close the stall guards to theirinefileetive position as shown in Fig. 2 so as not to interfere with thefreedom of movement of the animals.

What I claim as new and desire to secure l. A stall guard, comprising acollapsible guard frame adapted for connection with the divisionstandard of a stall frame for occupying space between said standard andthe adjacent stanchionsto prevent the animal entering its head betweenthe standard and the stanchions when driven into the stall.

2. A stall guard, comprising a collapsible frame in the form of aparallelogram adapted to be mounted on the division standard of thestall frame with its upright members forming guard bars positionedbetween the standard and the stanchions in the operative position of theframe.

3. A stall guard, comprising a pair of levers pivotally connected atintermediate .points .to the division standard of a stall of the levers,a bracket on one end of one of the was, and an operating rod extendinglengthwise of.the row of stalls and having the-bracket pivotallyconnected therewith.

5,. A stall guard, comprising a pair of levers having bracket arms toengage the division standard of a stall frame to form a pivotalconnection therewith and to form a stop for limiting the pivotalmovements of the levers by engaging the standard, guard bars pivotallyconnected to the levers adj acent both sides of the standard, and meansfor swinging the levers.

6. The combination with a row of stall frames provided with stanchionsand having division standards between the stalls, of guard meansoperatively connected together and extendingon either side of each ofsaid standards movable to positions between the standard and theadjacent stanchions and means for simultaneously operating said guardmeans.

7. The combination with a row of stall frames provided with. stanchionsand having division standards between the stalls, of guard meansoperatively connected together and pivotally secured to each of saidstand ards movable to positions between the standard and the adjacentstanchions to prevent the animals from enteringtheir heads between thestandard and the stanchions and means for simultaneously operating saidguard means.

8. The combination with a row of stall frames provided with stanchionsand having division standards between the stalls, of guard meansextending on either side of each of said standards movable to positionbetween the standard and the adjacent stanohions, and means forsimultaneously operating said guard means.

9. The combination, with a row of, stall frames providedwith stanchionsand having division standards between the stalls, of movable guardssecured to each of said standards for simultaneously occupying spacebetween each standard and the adjacent stanchions to prevent the animalsentering their heads between the standard and the stanchions when driveninto the stalls and 'means for simultaneously operating said guards.

10. The combination, with a row of stall frames provided with stanchionsand having -division standards between the stalls, of

movable guards mounted on the stall frames, means for simultaneouslymoving said guards to position between the standard and the adjacentstanchions to prevent the animals entering their heads between saidstandards and stanchions when driven into the stalls and to positionaway. from the stanchions when the animals are in the stalls to permitfree movement of the animals therein. a

In testimony whereof, I affix my signature, in presence of twowitnesses.
